Because these systems are revenue-critical and run continuously, we need someone who will see a problem through to resolution in production.\nWe are equally interested in how you work: pragmatic about tools and process, willing to make the call on what fits the problem in front of you, and able to raise the capability of the people around you rather than just your own throughput.\nRole accountabilities:\nWhat You'll Be Working On\nFeature-driven development within a distributed team of developers, testers, business analysts, and project managers.\nDesign, development, testing, and maintenance of secure services and applications across the tolling stack - roadside and lane software, back-office transaction and account processing, and customer-facing web and mobile channels.\nInterfaces to external systems - payment and financial processors, CRM platforms, IVR and contact centre systems, interoperability hubs, registry lookups, and third-party violation and collection services.\nSoftware deployment and support of production systems for various clients around the world.\nPeer review of solution designs, architectures, and code, and hands-on support when production issues arise.\nSoftware Development\nProvide senior-level, full-stack development across front end, back end, and database, with emphasis on systems design in a revenue-critical environment.\nBuild and extend back-office capability: transaction and trip processing, account and customer management, fare and toll rate configuration, money handling and settlement, video and image auditing, and violation processing.\nDevelop and maintain customer-facing web portals and mobile applications, and the APIs behind them.\nIntegrate with roadside and lane systems, automated payment machines, and customer display devices, working with the roadside team on interface definition and troubleshooting.\nDefine automated tests that prove the correctness of service logic, and optimize data storage and retrieval against SQL Server and Oracle databases.\nIdentify and mitigate security risks, participate in security reviews and vulnerability remediation, and support compliance obligations that apply to payment and personal data.\nSupport delivery and operations teams through deployments, upgrades, and production incidents, and work with client technical staff during integration, testing, and acceptance.\nMake effective use of modern development tooling, including AI-assisted coding tools, with sound judgment about where they help and where they introduce risk.\nTechnical Leadership\nProvide technical direction to other developers, and aid decision making by evaluating options for best fit.\nPerform code reviews with constructive, specific feedback, advocating for best practices and consistency.\nReview and advise on effort estimates and client feature requests, and contribute to technology stack evaluations and architectural direction.\nMentor developers, promote a culture of continuous learning and accountability, and drive improvement in quality and delivery efficiency.\nQualifications & Experience:\nMinimum seven years of professional software development experience.\nDeep practical knowledge of C# and .NET, including Web API.\nExperience with front-end technologies, particularly Angular and TypeScript.\nStrong relational database skills with SQL Server and/or Oracle, including query development, optimization, and support.\nComfortable working with AI-assisted development tools such as GitHub Copilot as part of day-to-day delivery.\nExperience delivering and maintaining customer-facing production systems, with a track record of owning issues through to resolution.\nUnderstanding of distributed systems, application of software patterns and pros and cons of different architectural choices.\nStrong grasp of the full software development life cycle, including CI/CD, testing strategy, and deployment practices.\nConfident, clear communication with clients as well as colleagues.\nBachelor's degree in Computer Science or a related field, or equivalent practical experience.\nNice to Have\nExperience with tolling, transit fare collection, payments, billing, or another revenue or transaction processing domain.\nFamiliarity with payment processing, PCI DSS obligations, or financial reconciliation and settlement.\nExperience integrating with CRM platforms such as Dynamics 365, or with contact centre and IVR systems.\nMobile development experience, or exposure to additional front-end frameworks such as React or Vue.js.\nExperience in a consulting or client-delivery setting, working across distributed international teams.\nWhy Arcadis?\nWe can only achieve our goals when everyone is empowered to be their best.
